Have Firefox blocked this and/or are there ways users can protect themselves?

"14 new types of 'XS-Leak' cross-site leak attacks against modern web browsers, including Google Chrome, Microsoft Edge, Safari, and Mozilla Firefox."

"These types of side-channel attacks are called 'XS-Leaks,' and allow attacks to bypass the 'same-origin' policy in web browsers so that a malicious website can steal info in the background from a trusted website where the user enters information.

"The principle of an XS-Leak is to use such side-channels available on the web to reveal sensitive information about users, such as their data in other web applications, details about their local environment, or internal networks they are connected to," explains the XS-Leaks wiki.

For example, an XS-Leak attack could help a background site siphon the email inbox contents from an active tab used for accessing webmail."

I was recently watching a Twitch livestream when I stepped away from my PC for a moment and upon returning found it sitting at the login screen. Checking eventvwr it showed a BSOD event had occurred. The only thing actively running on my PC was FireFox with a single tab for Twitch.

Level: Critical Source: Kernal-Power Event ID: 41 BugCheckCode: 307 decimal, 0x133 hex

Windows documentation lists hex 0x133 as a DPC_WATCHDOG_VIOLATION error, and since Parameter 1 was a '0', it states, "A single DPC or ISR exceeded its time allotment. The offending component can usually be identified with a stack trace." https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/bug-check-0x133-dpc-watchdog-violation

From Windows Debugging Tools I loaded up the DMP file and ran !analyze to see the process name listed as FF (there's more information listed, just not sure it's really useful).

I checked FF `about:crashes` and it doesn't show any crash report there (presumably because the system BSOD and it did not have a chance to do anything).

Just wondering if anyone else has seen this issue and how/if they resolved it. In searching around it seemed like some folks suggested disabling hardware acceleration as there may be incompatibility issues with FF and GPU drivers. I checked under FF settings and it has "Use recommended performance settings" enabled, but there are no sub-options specific for hardware acceleration.

Some basic system specs: MoBo: Gigabyte B550 Vision D-P (BIOS F13e, latest available) CPU: AMX Ryzen 7 5800X GPU: Gigabyte GeForce 3060Ti (driver 30.0.14.7141, latest one available)

Running on FF 94.0.2 (64-bit), the latest update.

Several weeks ago, because it seemed to be a Gmail-tab-only problem, Firefox Support advised us to contact Gmail Support.

It is now clear that the problem is with the Firefox browser. The attached screenshot shows an example of an affected tab.

Please fix this. Multiple versions of the same tab waste RAM and other memory, especially on a limited-memory device such as a laptop.

Good People, Followed screen pop-up to make Firefox default browser. Now all *.pdf files have Firefox icons and open as .html pages, I think! Seen some solutions, but for older versions of windows and followed procedure: go to Adobe, Edit, Preferences, General, 'Select Default PDF Handler', as dialog Does not have Adobe Reader XI, step two was Change to Adobe Reader DC, clicked continue, but NO Windows Configuration Screen appears. Using Version 94.0.2 (64bit) with Windows 10. Also, help answer said not necessarily a Firefox problem, also within Adobe Reader. Not comfortable with changes to be made in the registry. James

Continuing to have issues with pinned tabs and, worse, Firefox crashing...like y'day with loss of all pinned tabs on powering up today?! Have posted issue several times with "FredMcD" being unable to help but who escalated the problem...with no response from Mozilla/Firefox! Needlessly spending a great deal of time restoring pinned tabs but sometimes cannot find them all. Does the "800 lbs" Mozilla care?

Hello together.

I'm experiencing the same problem as discussed in this cases that is not solved yet: https://support.mozilla.org/en-US/questions/1312836 https://support.mozilla.org/en-US/questions/1333547 https://support.mozilla.org/en-US/questions/1321038

Symptoms: After FF starting it loads pages fast enough. After several minutes of using pages start be loading very slow. Loading slowness increases until it becomes blocked continuously. Reload button has no effect. I tried everything from here: https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can - No effect.

Work around done: When windows is loading in Safe Mode the problem disappeared. If I disable Windows Defender Firewall the the problem disappear and appear after firewall enabling again in several minutes (same as after FF restarting) When I go to <current network settings> and switch Network Profile from Public to Private or from Private to Public the problem disappear but goes back just in several minutes (same as after FF restarting). Windows 10 Restorehealth has no effect, and reports that everything is OK with system files (DISM.exe /Online /Cleanup-image /Restorehealth ) The most strange thing Windows 10 In-place Upgrade has no effect.


I found out the core of problem is that Windows Firewall is blocking FF internal interprocess communication on local TCP ports. Yes, you would say it is not possible and firewall doesn't affect local port communication but in my case it is a fact. I used the ProcessMonitor from Windows Sysinternals, and Windows Defender Firewall with Advanced Security log. Screenshots shows this fact. On first two lines from Firewall log you see a Local Port Communication blocking, on ports 1401 and 1400. Next Screenshot from ProcessMonitor shows (see blue colored lines) that it was exactly FF communication, where I was trying to reload a page several times.

Any ideas what to do with it? It seems like Microsoft’s way fighting a concurrent web browsers, but I hope it isn’t.

Now I use FF version 94 but the problem starts from 88. I was trying FF downgrading to version 75 with no effect.

I've browsed through a dozen of posts now and so far got my homepage to show me my local file. The problem is that I want this local file to also show when I open a new tab (Ctrl+T).

I've configured an autoconfig based on another post I read, currently have this:

In my autoconfig.cfg: // first line is a comment var {classes:Cc,interfaces:Ci,utils:Cu} = Components; var newTabURL = "path_to_my_file.html"; aboutNewTabService = Cc["@mozilla.org/browser/aboutnewtab-service;1"].getService(Ci.nsIAboutNewTabService); aboutNewTabService.newTabURL = newTabURL;

In my autoconfig.js: // pref("general.config.filename", "autoconfig.cfg"); pref("general.config.obscure_value", 0); //pref("general.config.sandbox_enabled", false);


I have the last line commented because it worked for the poster, but it gives me an error that firefox couldn't load my autoconfig and that I should contact my sysadmin, lol. Other than that error message, it worked the same as it does now after I closed the popup.

If possible I don't want to use any extensions for this.

I've been having an interesting problem with Firefox for the past couple of months regarding only Soundcloud, where after the first visit to the website it won't load, giving a generic "Sorry! Something went wrong" screen. Firefox will continue to not load the site correctly until I clear the cookies and the cache, which works but only for one visit, and as soon as I close the tab and open soundcloud again or refresh the tab the problem comes back. I have disabled all of my extensions as well as enhanced tracking protection when testing. A firefox refresh also did not solve the problem. The only way I can get the site to behave normally is when using private browsing.

The console is filled with errors regarding javascript files (source URI is not allowed in this document).

Thanks

Hi there,

I have a Firefox account which was registered using an email associated with a company I no longer work for. Since I have left the company, that email is inactive and I can no longer access it. This means that when I attempt to log into Firefox with that account, I cannot enter the verification / 2FA code because I cannot access the email.

Is there anyway I can close that Firefox account anyway? I do have the Firefox recovery key for that account though. I just wish for all the data associated with said account to be deleted.

Thanks

I cannot find any way to report problems, this seems to be the only way. When I try to open any PDF file, I have to Browse to find my pdf viewer (Flexipdf 2022). I do that and also check your "Do this automatically" option. Every time I try to open a pdf after that I still have to go through all the same Browse steps. I also set up Flexipdf 2022 in the Applications section of General Settings (Portable Document Format (PDF) (application/pdf)) and it is just deleted or never saved. The next time I look or try to use it, it’s gone. This is obviously a bug in your system, please correct. Thank You.
